Brad DeLong (after artfully denying that he would ever read Wonkette) points to an enlightening list at Human Events Online -- the Ten Most Harmful Books of the 19th and 20th Centuries. As voted on by leading conservative thinkers!

The Communist Manifesto, Marx and Engels

Mein Kampf, Adolf Hitler

Quotations from Chairman Mao, Mao Zedong

The Kinsey Report, Alfred Kinsey

Democracy and Education, John Dewey

Das Kapital, Karl Marx

The Feminine Mystique, Betty Friedan

The Course of Positive Philosophy, August Comte

Beyond Good and Evil, Friedrich Nietzsche

General Theory of Employment, Interest and Money, John Maynard Keynes

I love it. Mein Kampf snuggling right up there with The Feminine Mystique and The General Theory. (Because it's Keynes, you know, who is responsible for our huge budget deficit. Those damned liberals, always running budget deficits.)

But the list of runners-up is where it really gets good.

The Population Bomb, Paul Ehrlich

What Is To Be Done, V.I. Lenin

Authoritarian Personality, Theodor Adorno

On Liberty, John Stuart Mill

Beyond Freedom and Dignity, B.F. Skinner

Reflections on Violence, Georges Sorel

The Promise of American Life, Herbert Croly

Origin of the Species, Charles Darwin

Madness and Civilization, Michel Foucault

Soviet Communism: A New Civilization, Sidney and Beatrice Webb

Coming of Age in Samoa, Margaret Mead

Unsafe at Any Speed, Ralph Nader

Second Sex, Simone de Beauvoir

Prison Notebooks, Antonio Gramsci

Silent Spring, Rachel Carson

Wretched of the Earth, Frantz Fanon

Introduction to Psychoanalysis, Sigmund Freud

The Greening of America, Charles Reich

The Limits to Growth, Club of Rome

Descent of Man, Charles Darwin

Some of it is just amusing -- I mean, you might not be happy with Unsafe at Any Speed or Silent Spring, but "the most harmful books of the 19th and 20th centuries"? And what's up with John Stuart Mill, anyway?

But it's Darwin's appearance that is most telling. If this really does represent mainstream conservatism, its intellectual bankruptcy is showing.
